Abstract

An electrical terminal housing includes a housing body. The housing body defines a terminal cavity. An insertion opening in the housing body opens into the terminal cavity. A mate opening in the housing body also opens into the terminal cavity. A terminal lock extends from the housing body and is located in the terminal cavity. The terminal lock is adapted to engage an electrical terminal to retain the electrical terminal in the terminal cavity. The terminal lock is offset from the center of a side of the terminal cavity and is located closer to one side wall of the terminal cavity.

First claim

What is claimed is:

1. An electrical terminal housing comprising:
a housing body that defines a terminal cavity, an insertion opening in the housing body that opens into the terminal cavity, and a mate opening in the housing body that opens into the terminal cavity;
a first terminal lock including a first finger that extends from the housing body into the terminal cavity and a first lock boss located on the first finger that extends farther into the terminal cavity than the first finger, the first lock boss including a first portion that extends from the first finger into the terminal cavity and a second portion that extends from the first finger into the terminal cavity, wherein the first portion of the first lock boss extends farther into the terminal cavity than the second portion of the first lock boss; and
a second terminal lock including a second finger that extends from the housing body into the terminal cavity and a second lock boss located on the second finger that extends farther into the terminal cavity than the second finger, the second lock boss including a first portion that extends from the second finger into the terminal cavity and a second portion that extends from the second finger into the terminal cavity, wherein the first portion of the second lock boss extends farther into the terminal cavity than the second portion of the second lock boss.

2. The electrical terminal housing of claim 1 , wherein the first terminal lock includes a release surface between the first portion of the first lock boss and the second portion of the first lock boss, and wherein the second terminal lock includes a release surface between the first portion of the second lock boss and the second portion of the second lock boss.

3. The electrical terminal housing of claim 2 , wherein each release surface faces the terminal cavity and faces an end of the terminal cavity.

4. The electrical terminal housing of claim 2 , wherein the housing body includes a key opening that is aligned with the release surface.

5. An electrical terminal housing comprising:
a housing body that defines a terminal cavity, an insertion opening in the housing body that opens into the terminal cavity, and a mate opening in the housing body that opens into the terminal cavity; and
a terminal lock including a finger that extends from the housing body into the terminal cavity and a lock boss located on the finger that extends farther into the terminal cavity than the finger, the lock boss including a first portion that extends from the finger into the terminal cavity and a second portion that extends from the finger into the terminal cavity, wherein the first portion of the lock boss extends farther into the terminal cavity than the second portion of the lock boss.

6. The electrical terminal housing of claim 5 , wherein the terminal lock includes a release surface between the first portion of the lock boss and the second portion of the lock boss.

7. The electrical terminal housing of claim 6 , wherein the release surface faces the terminal cavity and faces an end of the terminal cavity.

8. The electrical terminal housing of claim 6 , wherein the housing body includes a key opening that is aligned with the release surface.

9. An electrical terminal housing comprising:
a housing body including four sides that extend from an insertion end to a mate end, the four sides of the housing body defining a terminal cavity having a substantially square cross-sectional shape that defines a terminal axis, each of the four sides of the housing body having a center that extends parallel to the terminal axis;
a first terminal lock that is adapted to retain an electrical terminal in the terminal cavity, the first terminal lock extending into the terminal cavity from a first one of the four sides of the housing body and being offset from the center thereof; and
a second terminal lock that is adapted to retain the electrical terminal in the terminal cavity, the second terminal lock extending into the terminal cavity from a second one of the four sides of the housing body and being offset from the center thereof.

10. The electrical terminal housing of claim 9 , wherein the first terminal lock includes a finger that extends from the first one of the four sides of the housing body and a lock boss that extends from the finger into the terminal cavity.

11. The electrical terminal housing of claim 10 , wherein the lock boss is divided into a first portion and a second portion that each extend from the finger into the terminal cavity.

12. The electrical terminal housing of claim 11 , wherein the first portion of the lock boss extends farther from the finger into the terminal cavity than the second portion of the lock boss.

13. The electrical terminal housing of claim 11 , wherein the first portion of the lock boss is further offset from the center than the second portion of the lock boss.

14. The electrical terminal housing of claim 9 , wherein the terminal lock includes a release surface that is adapted to be engaged by a key boss to move the terminal lock to a release position where the terminal lock is not adapted to retain the electrical terminal in the terminal cavity.

15. The electrical terminal housing of claim 14 , wherein the first terminal lock includes a finger that extends from the first one of the four sides of the housing body and a lock boss that extends from the finger into the terminal cavity, the lock boss is divided into a first portion and a second portion that each extend from the finger into the terminal cavity, and the release surface is located between the first and second portions of the lock boss.

16. The electrical terminal housing of claim 14 , wherein the housing body includes a key opening that is aligned with the release surface.

17. The electrical terminal housing of claim 16 , wherein the key opening is provided in the insertion end of the housing body.

18. The electrical terminal housing of claim 16 , wherein the key opening is provided in the one of the four sides of the housing body.

19. An electrical terminal housing comprising:
a housing body including four sides that extend from an insertion end to a mate end, the four sides of the housing body defining a terminal cavity having a substantially square cross-sectional shape that defines a terminal axis, each of the four sides of the housing body having a center that extends parallel to the terminal axis; and
a terminal lock that is adapted to retain an electrical terminal in the terminal cavity, the terminal lock extending into the terminal cavity from one of the four sides of the housing body and being offset from the center thereof, wherein the terminal lock includes a finger that extends from the one of the four sides of the housing body and a lock boss that extends from the finger into the terminal cavity, and wherein the lock boss is divided into a first portion and a second portion that each extend from the finger into the terminal cavity.

20. The electrical terminal housing of claim 19 , wherein the terminal lock includes a release surface between the first portion of the lock boss and the second portion of the lock boss.

21. The electrical terminal housing of claim 20 , wherein the housing body includes a key opening that is aligned with the release surface.
